Neural Network‐Based Detection of Adulterants in Opioid Samples Using IR Absorption Spectroscopy

Drug Testing and Analysis, EarlyView.
We construct a neural network for the classification of bromazolam and fluorofentanyl in illicit opioid samples. The model outperforms a random forest classifier and shows elevated performance for low concentration samples. ABSTRACT Community‐based drug checking services are challenged in their ability to reliably detect low concentration adulterants ...

Concentration and Detection Time of Nitrous Oxide in Blood Following Controlled Inhalation

Drug Testing and Analysis, EarlyView.
In a study with controlled inhalation of nitrous oxide (N2O), elimination followed a two‐compartment model with half‐lives of 2.4 and 31 min, and N2O remained detectable in blood samples for 1–3 h after inhalation. ABSTRACT Recreational use of nitrous oxide (laughing gas, N2O) is becoming increasingly common and abuse is often seen in relation to ...

High‐Adhesion Quadruple Hydrogen‐Bonded Ionogels: A Dual‐Function Platform for Gesture Recognition and Real‐Time NH3 Detection in Multiscenario

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Quadruple hydrogen‐bonded high‐adhesion ionogels for gesture recognition and real‐time NH3 sensing. Ionogels have garnered significant attention in flexible sensing due to their outstanding mechanical properties, conductivity, and stability. However, establishing a robust and stable adhesive interface with various substrates remains a significant ...

Interface‐Sensitized ZnO/WS2 Heterostructures: Surface‐Activated Porous Sensitizers for Robust Chemiresistive Gas Sensing

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced NO2 sensing mechanism of the P‐ZnO/WS2 heterostructure, emphasizing the role of the porous architecture and abundant chemisorbed oxygen species in P‐ZnO nanocubes, which facilitate interfacial charge transfer to WS2 nanoflakes. Hybridizing transition metal dichalcogenides with metal oxides offers a viable route to overcome their intrinsically ...
